Good way to handle relations?

[alexandernanberg]

Summary

I'm trying to figure out how to handle relations in a good way. I've read some other issues and the documentation but it still haven't "clicked" for me.

So I have a index.md file that looks like this and I want to somehow "pull" content from multiple other markdown files. In this case I use a relative path to reference the other files.

---
title: Lorem ipsum
featured_case:
  - ../case/case-1.md
  - ../case/case-2.md
---

I know it works it the featured_case wouldn't be an array but just the relative path to a file. Is there some straightforward way to enable this for arrays?

Is there another better way to do relations? I feel like using the path is the most robust way, since titles can change etc. And I'm not a big fan of the "mapping" solution, since that field will be added on all files if I'm not mistaken.

This apparently already works. You just have to change the query to be

featured_case {
  childMdx {
    frontmatter {
      title
      tags
    }
  }
}

replace childMdx with childMarkdownRemark if you'r not using MDX
